BMS Stage 1 for the N20/N26. $290. 2013+ Z4
Absolutely nothing wrong with it. Loved it while I had it but I have since moved on to other options. It's been on the car for about a year, looks new and works like new. This can be used on the electronic waste gate and pneumatic waste gate 28i engines. Easy plug and play set and forget. There are 3 or 4 pairs of connections to be connected depending on your engine type. (waste gate type) Local pick up would be great but I'd be willing to ship. Cheers.
